Hereinafter in this Resolution, the subject Conditional Use Permit, Variance and Tree Permit shall be referred to as the "Application." 2. On November 23, 2005, public hearing notices were mailed to approximately 180 property owners of record within a 1,000 -foot radius of the project site. On November 29, 2005, public hearing notices were posted in three public places within the City of Diamond Bar and the project site was posted with a display board. On December 1, 2005, notification of the public hearing for this project was provided in the San Gabriel Valley Tribune and Inland Valley Daily Bulletin newspapers. On November 23, 2005, in accordance to Public Resource Code, Section 21092.5, agencies responding to the project's Environmental Impact Report were notified in writing of the December 13, 2005, Planning Commission public hearing. 3. On December 13, 2005, the Planning Commission of the City of Diamond Bar conducted a duly noticed public hearing on the Application and continued the public hearing to January 10, 2006. 4. On January 10, 2006, the Planning Commission re -opened the public hearing and concluded the public hearing on the application. Planning Commission Resolution No. 2006-04 B. RESOLUTION. NOW, THEREFORE, it is found, determined and resolved by the Planning Commission of the City of Diamond Bar as follows: This Planning Commission hereby specifically finds that all of the facts set forth in the Recitals, Part A, of this Resolution are true and correct. 2. The Planning Commission hereby finds that the project identified above in this Resolution required an Environmental Impact Report (EIR). EER No. 2004-01 (SCH No. 200305102) has been prepared according to the requirements of the California Environmental Quality Act (CEQA) and guidelines promulgated thereunder. The 45 day public review period for the EIR began August 20, 2004, and ended October 4, 2004. Furthermore, the Planning Commission has reviewed the EIR and related documents in reference to the Application. 3. The Planning Commission hereby specifically finds and determines that, having considered the record as a whole including the findings set forth below, and changes and alterations which have been incorporated into and conditioned upon the proposed project set forth in the application, there is no evidence before this Planning Commission that the project proposed herein will have the potential of an adverse effect on wild life resources or the habitat upon which the wildlife depends. Based upon substantial evidence, this Planning Commission hereby rebuts the presumption of adverse effects contained in Section 753.5 (d) of Title 14 of the California Code of Regulations. 4. Based on the findings and conclusions set forth herein, this Planning Commission hereby finds as follows: (a) The project relates to vacant land located directly south of Rocky Trail Road and Alamo Heights Drive and west of Horizon Lane within a gated community identified as "The Country Estates" which consists of large single-family homes. The project site is directly south of Alamo Heights Drive which would be extended to provide access to the project site with Rocky Trail Road as a secondary emergency access. (b) The project site has a General Plan land use designation of Rural Residential (RR) Maximum 1 DUTAC. (c) The project site is within the Single Family Residence -Minimum Lot Size 20,000 Square Feet (R-1-20,000) Zone. However, Zone Change No.2005-03 within Planning Commission Resolution No. 2006-03 2 Planning Commission Resolution No. 2006-04 recommends that the City Council approve the zone change from R-1-20,000 to Rural Residential (RR) for General Plan compliance. (d) Generally to the north, south, east and west, the Single Family Residence -Minimum Lot Size 20,000 square feet (R-1-20,000) and R- 1-40,000 zoning districts surround the project site. (e) The Application request is to certify the Environmental impact Report; to subdivide a 80 acres site into 48 parcels with a minimum lot size of one acre for the eventual development of 48 single-family custom homes; to change the existing zoning from R-1-20,000 to Rural Residential (RR); to grade and develop in a hillside area; to allow retaining walls with an exposed height of more than six feet; and to remove and replace oak and walnut trees. Conditional Use Permit/Hillside Management The Planning Commission shall evaluate a Conditional Use Permit for hillside development based on the following objectives and required findings: (f) The preservation of natural topographic features and appearances by means of landform grading so as to blend man-made or manufactured slopes into the natural topography. The proposed map is a 48 lot residential subdivision for the eventual development of 48 single-family custom homes. The map approval includes grading the project site in a manner that will create buildable pads for each lot, Streets "A" and Street `B" within the map boundaries and the extension of Alamo Heights Drive and Lot A for open space revegetation and Lot B for sewer lift station. The proposed project will result in changes in the existing topography of the project site. Grading will create manufactured slopes at a 2:1 (horizontal to vertica)) ratio utilizing a landform grading technique. As a result, manufactured slopes will have characteristics resembling slopes created by nature. Round -off cut edges will be utilized to conform to the natural grade. Proper transitioning to natural slopes will be achieved through the use of irregular curvilinear shapes that will blend into the adjoining topography. Revegetation of the manufactured slope will be applied in patterns which occur in nature. Down slope drainage devices will be designed to follow the natural lines of the landform graded manufactured slopes, or tucked away in special swale and berm combinations in order to conceal the drains from view. Therefore, the proposed project will provide the appearance of natural topographic features by means of landform grading so as to blend man-made or manufactured slopes into the natural topography. 3 Planning Commission Resolution No. 2006-04 (g) The preservation of natural features and appearances through restrictions on successive padding and terracing of building sites. The proposed map is not the type of project that would tend to utilize successive padding and terracing of building sites. The project is located within a gated community that has a General Plan land use designation of Rural Residential which prescribes minimum lot sizes atone acre and with a maximum of one dwelling unit per acre. The zoning designation as prescribe in Zone Change 2005-03 for this project also requires minimum lot sizes of one acre with a maximum of one dwelling unit per acre. As such, the proposed map is in compliance with the General Plan and will be able to accommodate the applicable development standards of the RR zoning district as well as development standards set forth in the conditions of approval. (h) The retention of major natural topographic features, drainage courses, steep slopes, watershed areas, vernal pools, view corridors, and scenic vistas. The EIR (SCH No. 2003059 902) has been prepared for the proposed project and has analyzed visual impacts, scenic resources, drainage courses, watershed areas, steep slopes and vernal pools. Although the project site is currently undeveloped vacant land, it does not contain any unique aesthetic features or scenic resources. Topographic features and slopes have been addressed above in Finding (0 and with mitigation measures from the Mitigation Monitoring Program that will be incorporated into the proposed project, it is anticipated that the environmental impacts related to topographic features and slopes will be mitigated to a level of less than significant. Pursuant to the EIR, the proposed project site lies within the "Los Angeles -San Gabriel' Hydrology Unit and is in the San Gabriel River watershed boundaries. The watershed originates in the San Gabriel Mountains and eventually water discharges into the Pacific Ocean. For the project site, a drainage plan was prepared. The project site, as undeveloped land, does not contain any existing drainage facilities. Storm water currently drains into an un -named tributary of Tonner Canyon Creek. Off-site areas and manufactured slopes within the footprint of the project site would be routed via brow ditches to the southern project boundary. After construction of the project, storm water runoff from the site would continue to drain into Tonner Canyon Creek. Therefore, the existing drainage pattern would not be substantially altered. Additionally, vernal pools are not related to the proposed project. 4 Planning Commission Resolution No. 2006-04 According to the EIR, prominent visual characteristics of the project site are the natural landscape features, including the undeveloped hillside and the natural vegetation within the project boundaries. There are no exceptional or unique aesthetic features orscenic vistas present within the project boundaries. Only existing homes adjacent to the project site or on adjacent ridgelines have views of the project site. With the incorporation of mitigation measure such as: using landform grading techniques in order to minimize the visual impacts to the natural topography and maintain the look of natural slopes to the maximum extent; revegetation of manufacture slopes on the project site with natural and drought tolerant plant material; and the planting of vegetation associated with the future new homes will contribute to the visual continuity of the project site with the surrounding environment. As a result, aesthetic and visual impacts associated with the proposed project will be less than significant. (i} The preservation and enhancement of prominent landmark features, significant ridgeline, natural rock outcropping, protected trees and woodlands (Chapter 22.28, Tree Preservation and Protection), and other areas of special natural beauty; The preservation and enhancement of prominent landmark features and significant ridgeline is addressed in the above referenced Findings (t) and (h). According to the EIR, natural rock outcroppings do not exist at the project site. According to the EIR, focused surveys were prepared for native trees and special status plants/vegetation. The potential significance of environmental impacts on biological resources has been assessed. The proposed project will impact 7.94 acres of oak woodland and 5.20 acres of walnut woodland. It is estimated that approximately 348 coast live oak and 250 scrub oak and 279 southern California black walnut trees will be impacted by this project. The EIR concluded that with the implementation of mitigation measures as prescribed in the Mitigation Monitoring Program summarized as follows, it is anticipated that the proposed map and cumulative biological resources impacts would be reduced to a leve/ less than significant. The applicant will implement the mitigation plan, as approved by the City and according to the guidelines and performance standards of the plan. The mitigation measures are as follows: A combination of on-site or off-site preservation, enhancement, and/or restoration at no less than a 1:1 acreage ratio; 5 Planning Commission Resolution No. 2006-04 ■ Native free protection at a 3:1 ratio to replace 348 coast live oak trees, 250 scrub oak and 279 California black walnuts; ■ Biological monitoring;. ■ Obtain appropriate permits from California Department of Fish and Game, U.S. Fish and Wildlife Services, U.S. Army Corps of Engineers and State Water Resources Control Board; ■ Lighting plan reviewed and approved by the City demonstrating that lighting from the project will be directed away from natural open space areas. ■ Develop a planting schedule which requires planting to occur in late fall early winterbetween October 30, to January 30; and ■ Lighting plan reviewed and approved by the City demonstrating that lighting from the project will be directed away from natural open space areas. Ij) The utilization of varying setbacks,. building heights, foundation design and compatible building forms, materials, and colors which serve to blend buildings into the terrain. The proposed map will cause the eventual development of 48 custom single-family homes. The homes will be required to comply with development standards set forth by conditions of approval within this resolution that relate to setbacks, building height and the location of accessory structures. Additionally, future homes will be required to obtain approval through the City's Development Review process. Colors and material will be required to be compatible with other homes in the surrounding area. Furthermore, the City's Design Guidelines will also apply to the development of future homes. Foundation design will be required to comply with the California Uniform Building Code. (k) The utilization of clustered sites and buildings on more gently sloping terrain so as to reduce grading alterations on steeper slopes. As referenced above in Finding (g), the proposed map is not the type of project that would tend to utilize clustering of sites and building due to the General Plan land use designation and proposed zoning district which is in compliance with the General Plan. The project is located within a gated community that has a General Plan land use designation of Rural Residential which prescribes minimum lot sizes at one acre and with a maximum of one dwelling unit per acre. The zoning designation as prescribe in Zone Change 2005-03 for this project also requires minimum lot sizes of one acre with a maximum of one dwelling unit per acre. As such, the proposed map is in compliance with the General Plan and will be able to accommodate the applicable development standards of the RR zoning district as well 6 Planning Commission Resolution No. 2006-04 as development standards set forth in the conditions of approval. Furthermore, Finding (f) referenced above, discusses grading alterations on slopes. (I) The utilization of building designs, locations, and arrangements, which serve to avoid a continuous intrusive Skyline effect and which afford a few privacy and protection; At this time, the construction of residential units is not part of the application request. The future development will be required to obtain approval through the City's Development Review process and comply with the City's Design Guidelines and comply with development standards set forth in this resolution. This process analyzes building designs, locations, and arrangements, privacy and protection. {m) The preservation and introduction of plant materials are to protect slopes from soil erosion and slippage and minimize the visual effect of grading and construction and hillside area. Grading will create manufactured slopes at a 2:1 (horizontal to vertical) ratio utilizing a landform grading technique. As a result, manufactured slopes will have characteristics resembling slopes created by nature. Round -off cut edges will be utilized to conform to the natural grade. Proper transitioning to natural slopes will be achieved through the use of irregular curvilinear shapes that will blend into the adjoining topography. Revegetation of the manufactured slopes will be applied in patterns which occur in nature, thereby minimizing the visual effect of grading. The revegetafion will be accomplished with suitable plant material requiring minimal cultivation and irrigation in order to thrive, thereby fostering slope stability and minimizing the potential for erosion. (n) The utilization of street designs and improvements which serve to minimize grading alterations and harmonize with the natural contours and character of the hillside. The proposed project is located directly south of Rocky Trail Road and Alamo Heights Drive and west of Horizon Lane. The project proposes two streets, identified as Streets "A" and `B" and the extension of Alamo Heights that will be the main access to the project site. However, the applicant will be required to improve and extend Alamo Heights Drive to align with and be compatible with approved Vesting Tract Parcel Map No.53670. All improvements and the extension of Alamo Heights Drive will be constructed to the satisfaction of the City Engineer. 7 Planning Commission Resolution No. 2006-04 Variance (o) There are special circumstances applicable to the property (e.g., location, shape, size, surroundings, topography, or other conditions), so that the strict application of the City's Development Code denies the property owner privileges enjoyed by other property owners in the vicinity and under identical zoning districts or creates an unnecessary and non -self created, hardship or unreasonable regulation which makes it obviously impractical to require compliance with the development standards. In accordance to Development Code Section 22.52.020, an application for a Variance may be filed and considered in order to increase retaining walls heights from the allowed six feet depending on topography constraints. The applicant proposes retaining walls throughout the project site due to the topography of the site and grading activities related to cut and tills that are needed to prepare the site for 48 lots with buildable pads, streets and access points. Several of the proposed grading walls are in excess of the maximum allowed exposed height of six feet. The retaining walls in excess of the allowed six foot height are as follows: Lot 31 The applicant is required to provide a five foot wide planter area located adjacent to the pad and the first retaining wall and landscape the planting areas to reduce the visual and aesthetic impact from Street "A" and Lot 39. Lots 25 and 26 The wall shall be designed as two walls, thereby reducing the height of each wall with planting areas between the walls to reduce the visual impact. Lot A The retaining walls proposed for the trail easement/maintenance road will remain at the 10 foot height. These walls vary in their linear design and will not create a tunnel effect (i.e., walls on both sides of the trail) and their impact can be reduced by the plant material. The retaining wall proposed along Alamo Heights for the purpose of constructing the road is needed due to elevations of existing lots that have rear property lines at Alamo Heights and to align with and be compatible with the extension of Alamo Heights that will serve approved Vesting Tentative Tract Map No. 53670 (Yeh/five lot 8 Planning Commission Resolution No. 2006-04 subdivision). The applicant has a 40 foot easement to grade and construct this retaining wall. However, the applicant is working with the owners of Lots 4, 5, 6, 7, 8, 9, and 10 of Tract 32482 and Lot 96 of Tract 30578 in order to gain an additional 50 foot easement. The additional 50 feet will eliminate the proposed retaining wall and in its place will be a landscaped 2:1 slope adjacent to Alamo Heights. The slope will be planted and maintained by the applicant and eventually by the homeowners association of the proposed map. In the event, that the applicant does not gain the additional 50 foot easement, this retaining wall will be designed and constructed as two walls with landscape area between the walls. All retaining walls proposed on Lots 25 and 26, Lot "A" and on the west side of Alamo Heights will be constructed from Architectural Shotcrete with pockets that will contain plant material and irrigation. The Shotcrete has a natural rock appearance and the pockets of plant material will enhance that natural appearance. All other retaining walls will be constructed from decorative material such as split face block. (p) Granting the Variance is necessary for the preservation and enjoyment of substantial property rights possessed by other property owners in the same vicinity and zoning districts and denied to the property owner for which the Variance is sought. As referenced above in Item (1), granting the Variance is necessary for the preservation and enjoyment of substantial property rights possessed by other property owners in the same vicinity and zoning districts and denied to the property owner for which the Variance is sought due to the constraint of the project site caused by topography as described in Finding (1) above. (q) Granting the Variance is consistent with the General Plan and any applicable specific plan. Due to the constraints of the project site related to topography and an increase in wall heights will allow the applicant to develop the project site with buildable pads, service road/trail easement and the extension of Alamo Heights which is the main access to the project site. Therefore, granting the Variance will be consistent with the General Plan. The project area does not have a specific plan. (r) The proposed entitlement would not be detrimental to the public interest, health, safety, convenience, or welfare of the City. 9 Planning Commission Resolution No. 2006-04 Before the issuance of any City permits, the proposed project is required to comply with all conditions within the approved resolutions for this project, landscaping requirements for screening the walls along with Architectural Shotcrete for wall construction and the Building and Safety Division, Public Works Department, and Fire Department requirements. The referenced agencies through the permit and inspection process will ensure that the proposed project is not detrimental to the public health, safety or welfare or materially injurious to the properties or improvements in the vicinity. (s) The proposed entitlement has been reviewed in compliance with the provisions of the California Environmental Quality Act (CEQA). The Planning Commission hereby finds that the project identified above in this Resolution required an Environmental Impact Report (EIR). EIR No. 2004-01 (SCH No. 200305102) has been prepared according to the requirements of the California Environmental Quality Act (CEQA) and guidelines promulgated thereunder. The 45 day public review period for the EIR began August 20, 2004, and ended October 4, 2004. Furthermore, the Planning Commission has reviewed the EIR and related documents in reference to the Application. Tree Permit (t) Preservation of the tree is not feasible and would compromise the property owner's reasonable use and enjoyment of property or surrounding land and appropriate mitigation measures will be implemented in compliance with Section 22.38.130 (Tree Replacement/Relocation Standards According to the EIR prepared for the project site, focused surveys were prepared for native trees and special status plants/vegetation. The potential significance of environmental impacts on biological resources has been assessed. The proposed project will impact 7.94 acres of oak woodland and 5.20 acres of walnut woodland. It is estimated that approximately 348 coast live oak and 250 scrub oak and 279 southern California black walnut trees will be impacted by this project. The EIR concluded that with the implementation of mitigation measures as prescribed in the Mitigation Monitoring Program summarized as follows, it is anticipated that the proposed map and cumulative biological resources impacts would be reduced to a level less than significant. 10 Planning Commission Resolution No_ 2006-04 The site for off-site mitigation will be determined in coordination with the project applicant, the City and resource agencies; A combination of on-site or off-site preservation, enhancement, and/or restoration at no less than a 1:1 acreage ratio; ■ Native tree protection at a 3:1 ratio to replace 348 coast live oak trees, 250 scrub oak and 279 California black walnuts; ■ Biological monitoring; ■ Obtain appropriate permits from California Department of Fish and Game, U.S. Fish and Wildlife Services, U.S. Army Corps of Engineers and State Water Resources Control Board, ■ Lighting plan reviewed and approved by the City demonstrating that lighting from the project will be directed away from natural open space areas; and ■ Develop a planting schedule which requires planting to occur in late fall early winter between October 30, to January 30; 5. Based on the findings and conclusions set forth above, the Planning Commission hereby recommends that the City Council certify the Environmental Impact Report (SCH No. 2003051102) and recommends that the City Council approve TTM 53430 and the Mitigation Monitoring Program subject to the following conditions and Standard Conditions attached and referenced herein: a.
